1. 在创建的组中实现只能选中一个项目

<Window
        xmlns="//schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="//schemas.microsoft.com/winfx/2006/xaml"
        xmlns:dxb="//schemas.devexpress.com/winfx/2008/xaml/bars" 
        xmlns:dxe="//schemas.devexpress.com/winfx/2008/xaml/editors"
        xmlns:dx="//schemas.devexpress.com/winfx/2008/xaml/core" x:Class="WpfApplication302.MainWindow"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <DockPanel>
            <dxb:ToolBarControl Caption="Edit" DockPanel.Dock="Top">
                <dxb:BarItemSelector>
                    <dxb:BarCheckItem Glyph="{dx:DXImage Image=3DColumn_16x16.png}"/>
                    <dxb:BarCheckItem Glyph="{dx:DXImage Image=3DFullStackedArea_32x32.png}"/>
                    <dxb:BarCheckItem Glyph="{dx:DXImage 

2. 报表打印

using System;
using System.Windows.Forms;
using DevExpress.XtraReports.UI;

namespace PrintReport {
    public partial class Form1 : Form {
        public Form1() {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e) {
            // Create a report instance, assigned to a Print Tool.
            ReportPrintTool pt = new ReportPrintTool(new XtraReport1());

3. 手动添加DXSplashScreen控件

// How to manually invoke and close DXSplashScreen
// 
// This example shows how to manually invoke and close DXSplashScreen. By default,
// DXSplashScreen contains a progress bar, indicating the progress of the
// application load. This example also shows how you can manually change the
// progress in code.
